intoplace. This.

'portant a Itis customary to shovel this col ie into the pits by handand then scrape or poke it is an extremel hot and laborious task, and itis diflicu t for the workmen to lace the coke in the bottpin of the pitto thegiest advantage. It is desirable that'the coke be thrown againstthe walls of the pit for. the purpose of protecting the latter. At thesame time it is desirable that .the coke be so laced as to make a troughation'of slag and also proof the ingots in the pits. It is very imsothat the distribution of the coke dust ove the bottom be-uniform, thatis to say, it should not be piled high on one 'vention is to facilitateside and low on the other. n

One. of the ob ects, therefore, of my inthe proper covering of thebottom of soaking-pits.

4 Another object is to preserve the walls of soaking-pits.

Another object is to deposit coke dust in the soaking-pits in a mannerto properly accumulate all the slag.

Generally speaking, jects are accomplished by providin a portable hopperfor discharg ng coke ust into soaking-pits, including a bottom forcausing the contents of the hopper'to be discharge towardthe walls andtoward the middle of the it; p T e invention is illustrated on theaccompanying sheets of drawings, in which- Figure 1 is a sectionaleleyation of my hopper shown in connection with" a soaking pit; and,Fig. 2 an enlarged scale.

the hopper in the ho per is these and other obis a plan view of thehopper on The various novel features of the inven tion will be apparentfrom the following description anddrawings and will be particularlpointed out in t e appended claims.

y ho per 10 is provided with 9. rec-' ortion including four walls thebody portion of the hopper are laterally extending arms or frames 18 and19 whic are adapted to rest res 'ectiv'ely. he hopper is adapted toswing froma crane bymeans of a ail 22 secured to two ieces 28 which areconnected to each other m intersectin planes. These two pieces 23 cavertica ly extending members" 24, a) the ower ends of which members issecured the hopper-bottom 25. Thisho per bottom includes two s acedpeaked members 26, each of which is a a ted to shed the contents ofaterally opposite directions toward the walls 27 and toward the middleof the soakin it 28 over which the hopper proper may removabledownwardly from the'bo y portion of the hopper, whereby the contents ofthe hopper may be deposited readily into the ,pit 28.

By-means of a crane, the hopper is carried 7 to the pit loaded with cokedust and lowered into a position such that its laterally ex-.

protect the same against radiatedz' 'na the hot i etc which later aredeposited in the pit.

t the same time ottom of the.

out from the hopper in a When the crane lowers an inthe coke dust whichis discharged inwardly over the inner shedding surfaces of the peaks 26is directed toward the middle of the pit. As a result of this guideddischarge of the coke dust from the hopper, the coke dust is piledsomewhat higher at the sides and at the middle of the pit runninglongitudinally thereof and forming therebetween suitable troughportions29 for the accumulation of slag and the proper placing ofingots. Generally speaklng, the coke dust 30 is automaticallydistributed quite uniformly over the bottom, there being no positing thelowering the bottom to permit the contents necessity for the workmen torake or otherwise distribute the coke in a less efiicient manner.

This method of distributing coke dust in soaking-pits greatly simplifiesand improves formermethods, and consists in filling the hopper havin aremovable bottom, then deopper over the pit, and then of the hopper tobe distributed in a given 'manner. It will be noted thatthe {topper as aunit is suspended from the ottom thereof.

There may be various modifications of ne invention herein particularlyshown and described, and it is my intention to cover all suchmodifications which do not involve a departure from the spirit and scopeof the invention as set forth vin the followin claims.

-I claim: 1. The herein describedmethod which consists in supporting aquantity of pulverulent lining material at the open top of a; soakingpit, showering the supported material down upon the bottom of the pitand at the same time directing the material to form a trough of thematerial upon the bottom of the pit.

2. The herein described methodwhich consists in supporting a quantity ofpulverulent lining material at the open top of a soaking pit, showeringthe supported material down upon the bottom of the pit and causing thematerial to hill up around the side walls of the pit.

3. The herein described method which consists in .supporting a quantityof pu1ver-' ulent lining material at the open top of a soaking pit,showering the supported material down upon the bottom of'the pit,;and

- causing the material to hill'up around the .verule'nt lining materiaside walls of the pit and also diametrically across the bottom of-thepit to form troughs at opposite sides thereof.

4. The herein described method of lining soaking pits while in aheated.condition, which consists in ta-kinig an amount of pulbottom ofthesoaking pit and supporting said material at the showering the'materialdown upon the botof the sufficient to line the 'open' top of the pit,

the material to-cm'er the entire bottom area of the pit. 1

5. The combination witira soaking pit, of portable lining distributingmeans supported over the mouth of the pit-and including a hopper tocontain a supply of pulverulent lining'material, and mechanism fordistributing the pulverulent material from the hopper and upon thebottom of the pit as a lining for said bottom.

. 6. The combination with a soaking pit, of

portable lining distributing means supported over the mouth of the pitand including ahopper to contain a supply of pulverulent liningmaterial; and mechanism for distributing. the pulverulent material fromthe hopper andupon the bottom of the pit as a lining thereof and in atrough formation on the bottom of the pit.

7 The combination with asoaking pit, of

portable mechanical means for distributing pulverulent material withinthe pit as a li1img for the bottom thereof, and including a frame torest at opposite sides of the pit, a hopper carried by the frame, and adistributing hopper-bottom capable of being lowered with respect to thehopper to discharge the contents of the hopper into the pit. 8. Thecombination with a soaking pit, of portable mechanical means fordistributing pulverulent material within the pit as, a lining for thebottom thereof, and including a frame to rest at opposite sides of thepit. a hopper carried by the frame, a distributing hopper-bottom capableof being lowered with respect to the hopper to discharge the contents ofthe hopper into the pit, and a hoisting element associated with thehopperbottom, whereby the hopper may be transported and the hopperbottomlowered and raised with respect to the hopper.

9. A portable distributing hopper for soaking pits, comprising a hopperbody, hopper supporting means carried by and ex ten-ding laterallyoutward from the hopper body and adapted to rest-at opposite sides opentop of a soaking pit and support the hopper over the top of the pit, adistributmg hopper-bottom capable of being lowered with respect to thehopper to discharge the contents of the hopper, and a hoisting elementassociated with the hopperbottom whereby the hopper-bottom may be raisedand lowered and the hopper transported. 1

of the pit to supply pulverulent lining ma- 1 means to guide and directthe 1 tom, said depress'ble closure and t e open bottom of the hopperbeing provided with cooperating means to guide and direct thedischarging material and. cause the same to hill up around the uprightwalls of the pit and across the bottom t ereof and form lining materialinto one or more troughs.
